在 Java 中将数组分配给 ArrayList [英] Assigning an array to an ArrayList in Java

问题描述

是否可以在 Java 中将 array 分配给 ArrayList?

Is it possible to assign an array to an ArrayList in Java?

推荐答案

您可以使用 Arrays.asList():

You can use Arrays.asList():

Type[] anArray = ...
ArrayList<Type> aList = new ArrayList<Type>(Arrays.asList(anArray));

或者，Collections.addAll():

ArrayList<Type> aList = new ArrayList<Type>();
Collections.addAll(theList, anArray); 

请注意，您并不是在技术上将数组分配给 List(好吧，您不能这样做)，但我认为这是您正在寻找的最终结果.

Note that you aren't technically assigning an array to a List (well, you can't do that), but I think this is the end result you are looking for.
